Two weeks ago I took it to a Honda dealership for them to fix it.  They checked it and told me “it just wants a software update.”  (How did it know an update was available?)

So they did it, and lo and behold, the light was off.

The following Monday, the light was back on.  It stayed on all last week, until Sunday, when apparently it wasn’t on.  It wasn’t on yesterday either, but I took it in to the dealership anyway.

They looked at it and couldn’t see anything wrong, but they did say some other cars are having the same issue.  He told me “maybe it’s the cold.”

Well that’s just great.  I have a “check engine” light that’s gimped by cold weather.  How am I supposed to know whether my engine is actually breaking, if it’s cold outside?
